Abstract

A swing structure for a wheel set includes a central tube, an axial tube, a spacer, a sleeve, and a fastener. The central tube is provided with a ring plate at the rear end. The ring plate is formed with a through hole thereon. A connection cylinder is disposed at the middle section of the axial tube. The connection cylinder has one end provided with a ring plate. The ring plate of the connection cylinder has a through hole for the sleeve to insert through. The spacer has a through hole for the sleeve to insert through. The sleeve is hollow for the fastener to insert through. The fastener inserts through the sleeve and is secured in the through hole of the ring plate of the central tube.

Description

    BACKGROUND OF THE INVENTION
  • (a) Field of the Invention
  • The present invention relates to a swing structure for a wheel set applied to a kick scooter or a children's tricycle, which is free to swing at a certain angle without the risk of turning over.
  • (b) Description of the Prior Art
  • Whether two wheels are used in the front or in the rear on certain kick scooters or children's tricycles, a single-wheel turning mechanism is adopted. In case of a wild turning, either of the front or rear wheels, i.e., the outside one, can easily leave the ground to cause the scooter to turn over. Therefore, it is necessary to limit the swing angle to stay within a safe range.
  • Furthermore, when driving on a rough road, the scooter tends to be elevated higher on one side to cause the standing board of the scooter is to be inclined, making the rider of the scooter uncomfortable.
    • SUMMARY OF THE INVENTION
  • The primary purpose of the present invention is to provide a swing structure for a wheel set, which is free to swing at a certain angle, free of risk of turning over due to wild swing, compact in construction and at low production cost. To achieve the purpose, the present invention includes a central tube, an axial tube, a spacer, a sleeve, and a fastener. A ring plate having a through hole is disposed at the rear end of the central tube. A connection cylinder is disposed at the middle section of the axial tube. One end of the connection cylinder is provided with a ring plate having a through hole for the sleeve to insert through. The spacer has a through hole for the sleeve to insert through. The sleeve is hollow for the fastener to insert through. Accordingly, the fastener inserts through the sleeve and is secured in the through hole of the ring plate disposed at the rear end of the central tube. The through hole of the ring plate of the central tube is a threaded hole and the fastener is a bolt.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is an exploded view of a preferred embodiment of the present invention.
  • FIG. 2 is a perspective view of the preferred embodiment of the present invention as assembled.
  • FIG. 3 is a cross-sectional view of the preferred embodiment of the present invention.
  • FIG. 4 is a perspective view of the preferred embodiment of the present invention in an operating status.
    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring to FIGS. 1 and 2, a preferred embodiment of the present invention comprises a central tube (1), an axial tube (2), a spacer (3), a sleeve (4), a fastener (5) and a tube plug (6).
  • A ring plate (11) is provided at the rear end of the central. tube (1). A through hole (111) is disposed on the ring plate (11). In this embodiment, the through hole (111) is a threaded hole.
  • A connection cylinder (21) is provided at the middle section of the axial tube (2). One end of the connection cylinder (21) is provided with a ring plate (211). A through hole (212) is disposed on the ring plate (211) for the sleeve (4) to insert through.
  • The spacer (3) is made of plastic material and has a through hole (31) for the sleeve (4) to insert through.
  • The sleeve (4) is hollow for the fastener (5) to insert through.
  • The fastener (5) is a bolt in this embodiment.
  • The tube plug (6) is to cover up the connection cylinder (21).
  • As shown in FIG. 3, the fastener (5) inserts through the sleeve (4) and is fastened in the through hole (111) of the ring plate (11) of the central tube (1), so that the connection cylinder (21) of the axial tube (2) is pivotally connected to the central tube (1) and the spacer (3). The tube plug (6) covers up the connection cylinder (21). Accordingly, the connection cylinder (21) of the axial tube (2) is allowed to swing in relation with the central tube (1). The spacer (3) disposed between the ring plate (211) of the connection cylinder (21) and the ring plate (11) of the central tube (1) provides proper tightness and wear-resisting performance.
  • As illustrated in FIG. 4, the preferred embodiment of the present invention is applied to the rear wheel set of a kick scooter. When the scooter is taking a turn or driving on a rough road, the rear wheel set swings in safe and free fashion within the range of a certain angle without the risk of turning over due to wild swing.
